DS1972-F3+

The DS1972-F3+ is a 1024bit EEPROM iButton in a rugged F3 iButton® package. This 1-Wire® EEPROM chip is organized as 4 memory pages of 256bit each. Data is written to an 8byte scratchpad, verified and then copied to EEPROM memory. The 4 memory pages can individually be write protected or put in EPROM emulation mode where bits can only be changed from 1 to 0 state. Chip based data carrier stores digital identification and information. The DS1972 communicates over single conductor 1-Wire® bus and communication follows standard 1-Wire® protocol. Each device has its own unalterable and unique 64bit ROM registration number that is factory lasered into the device. The registration number is used to address the device in a multidrop, 1-wire net environment. The device is used in access control/parking meter, work in progress tracking, tool management, inventory control and maintenance/inspection data storage applications.
